[求助] Questions about Relativist​ic effects in VASP

In the paper (Ab-Initio Simulations of Materials Using VASP: Density-Functional Theory and Beyond, J Comput Chem 29: 2044–2078, 2008), it states “In the standard mode, VASP performs a fully relativistic calculation for the core-electrons and treats valence electrons in a scalar relativistic approximation.”

I am not clear how VASP includes full relativistic effects for core-electrons. what relativistic calculation is VASP performing for the core? Does it use the relativistic K-S equations when solving for the core electrons? Is the scalar relativitic approximation treated for valence electrons via PAW potentil? What approximation is this (e.g. ZORA, IORA, DKn, IOTC, etc.)?

记得在vasp tutorial里面的magnetic properties那一章看到过 pseudopotential是scalar relativistic的 spin-orbital coupling是在PAW的hamitonian里加的 什么近似的不太知道 一知半解 不好意思 太理论了
